ounted in suitable hearings in the main frame 1 is a driving shaft 2. vSecured to shaft 2 are cams 3 which forma groove 4 in which a roller 5 attached to a lever 6 travels, thereby causing oscillating move .ment of saidlever. One end of lever 6 is pivoted at 7 to the main frame, the other end being connected by a link 8 to a slide 9 which has reciprocating movement in guides 10. e Y

Forming part of slide 9 is an upward extension 11 having -a'bearing in which is fitted a shaft 12. Shaft 12 is journaled in bearings 13, 14 and 15. Shaft 12 is provided with a. screw thread 16, nuts 17, and jam nuts 18, .on each side of the extension 11, so that the nuts 17 can be adjusted to fit close to the extension, whereby reciproeating movements of slide 9 cause like movements of shaft12. Secured to shaft 12 is a series of plunger arms 19, 20, 21 and 22, and an arm 23. 1

Located between bearings 14 and 15 is a sleeve 24, through which shaft 12 has reciprocating movement. Sleeve 24 is provided with a spline 25 which rides in a. groove 26 formed in shaft 12. Forming.

.part of sleeve 24 is an arm. 27, which is connected by a link 28 to one end of a lever 29 pivoted at 30 to the main frame. Secured to the other end of lever 29 is a roller 31 which'engages a cam 32 secured to the driving shaft 2. Action of cam 32 on lever 29 causes sleeve-24, shaft 12, together with the lunger arms 19, 20, 21 and 22, and arm 23, fixed thereto, to have an oscillating or rocking movement.

A horizontal channel divided'into sections having an opening along one side, forrper= mitting movement of. plunger arms 19, "20,

34 and 39 and the channel section for-med by 1 21 and 22, is formed by upper plates 33, 34, 35, 36 and 37 and correspondlng lower plates 38', 39, 40, 41 and 42, and by meansof upper'and lower plates 43 mounted in forks 44 and 45. I

Forks 44 and ,45 are secured standards The fork 44 is interposed between the channel section formed by plates to shafts 46 which are journaled in bearlngs formed on? upward through holes formed in stationary V plates 51, said bolts being screw threaded to receive thumb nuts 52 Between the sta-' tionary plates 51 and sald upper plates are springs 53 which are riveted to the upper plates, said springs serving to force the upper plates downward until checked by engagement of the nuts 52 against the stationar plates, as shown in F lgs. l5 and 37. In igs.14, 15,19, 31, and 37, parts of the machine are shownladjusted to the position they occupy when .articles of little.

height are to be wrapped. When articles of greater height are to bewrapped, theupper plates 33, 34, 35, 36 and 371 are raised and a plate or washer 54 is placed between the; nuts 52 and the stationary plates 51.

The forks 44 and 45 are also raised and held hen plates 43 having side walls 56- of less height than those shown in Fig. 15 are mounted on the forks. The plates. 43 are slid onto the forks until the plates reach a stop 57, and are held in place by means of a screw 58 at .the outer end ofthe folks.

The plates 43 of fork 44 are inclo-sed byelastic sleeves 59, and the upper plates 34-, i

35 and lower plates 39, 40 of the channel sections are also inclosed by elastic'sleeves 60. The purposev of said elastic is to effect frictional engagement with the inner wrapper suiiici'ent. to force the wrap-per against the artlcle, wlthoutinjury to'the wrapper or to the article. a

Secured to the shaft 46 forming part; of

fork 44 is a bevel gear wheel 61 which is in mesh wlth a bevel'gear wheel 62 secured to a vertical shaft 63. Secured to vertical shaft 63- isa wheel 64 having twd'series of gearfteeth 65 formed on its circumference and concave surfaces, 66,, between said series of gear. teeth. The gear teeth 65 mesh: with 5 gear teeth .67.formed on a fourth part off the circumference of a wheel 68-which is. secured to a vertical shaft 69. A concentric I surface'70 extending through three fourths of the circumference of wheel 68 is adapted to fitagainst a concave surface 66 of wheel 64.

Secured to shaft 69is a bevel gear wheel 71 Whichis in mesh with a bevel gear wheel 72 securedito the,driving shaft 2.: Said gearing causes-rotation of shaft 69 and wheel 68 in the direction indicated by the arrow in F ig.'4. During three-fourths of the revolution of shaft 69 the concentric surthe plates 35 and 40.- Each of flthe upper *face 70 fitting the concave surface ,'66 will and-lower plates 43 isprovidedwith flanges 48, and the forks 44 and 45 are provided with springs 49 v which force the plates toward eaqhother until checked by engagement of flanges 48 with the forks.

Each. of'theupper lates 33, 34, 35, 3e. and 65 are provided with bolts 50 which extend cause the wheel 64, shaft. 63, bevel gear "nel.

' 1,1oapa4 Secured tothe shaft 46 forming part of fork 44 is a gear wheel 73 which is in mesh with'a gear wheel 74 'securedto a shaft 75. Secured to the shaft 75 is a chain wheel 76 -over which rides an endless chain 77, said chain also riding over a chain wheel 78 jwhich is secured to the shaft 46lforming part of fork 45. It will be evident that said gearing andchain connection 'will cause rotatlon of fork in a direction opposite to that of fork 44. I

A chute 79 for reception of an inner wrapper a extends across the channel formed by upper plates 33, 34, and lower plates 38, 39, and is provided with supports 80 for. sustaining the wrapper in such man ner that the ortion extending below the channel excee s the portion above the chan- A chute 81 for reception of an, outer wrapper .b extendsr across the channel formed by upper plate 36 and lower Plate 41,- .and is provided with su ports 82 for sustaining the wrapper in-suc manner that the portion of wrapper extending above.

the channel exceeds the portion below the channel. t Y

Securedtoflriving shaft 2 is a wheel 83,

Thavinggear teeth 84 and a concentric surface 85 so proportioned to each other that the; concentric surface occupies one-fourth and'the gear teeth'three-fourths of thecircumference; of the wheel... The concentric surface 85, rides in concave surfaces 86 formed in the periphery'of a wheel 87, said wheel having gear teeth 88 which are adapted to mesh with thegear teeth 84. of wheel -83. Wheels 83 and 87 are so proportioned to each other that when the gear teeth are in mesh, three-quarters 'of, a revolution of wheel '83' will cause one half of a'revolution ofwheel 87. WVheel 87 is secured to a short shaft 89, to which is secured a chain wheel 90. l

An endless'chain 91 driven intermittently by chain wheel.90 rides'over chain wheels 2 and 93'and also over a pulley 94 which is journaled at 95 upon an adjustable slide 96. The chain 91 is provided with a series of arms 97 and the chain wheel 89is provided with recesses .98 into which the arms pass during travel of the chain over the i wheel. The portion of said chain extending straight line.

from pulley 94t'o chain wheel 92 is provided with a straight support 99 which causes the upward extending arms'97 to travel in a A series of articles 0 are placed upon supports 100 in suchmanner that each article is in advance of one of the arms 97. Each of the arms 97 is provided -With a right angular extension 101 which engages the upper side of thearticle as shown'in Fig. 16. During each movementof the chain 91 the attached'arms 97 cause a corresponding movement of the" series of articles. A pair of knives 102 are fixed in such manner that during succes'sivemovements of the articles the sides of the articles are trimmed by means of the knives. Successive movements of the chain 91 cause one of thetrimmed articles to be moved to rest between the vertically yielding upper plate 33 and the lower plate 38, and in front of the plunger arm 19. Forward longitudinal movement of the rock-shaft 12 then causes the plunger arm 19 to move the article and wrapper a between thecanvas covered plates 34'and'39, thereby causing-the wrapper to be folded upon the article'in the .manner shown in Fig.5. Said forward longitudinal movement of the rock-shaft also causes plunger arm 19 to move said article and wrapper between the canvas covered plates 43 of fork 44. During said forward longitudinal movement of the rock-shaft 12, the arm 23 secured thereto travels in a guide 103 formed in a stationary part 104 of the machine, thereby causing the series of attached plunger arms 19, 20, 21 and 22 to travel in a straight path along the wrapper folding channel. Rocking movement ofshaft 12 then causes downward swingingmovement .of said series of plunger. arms to the position shown by the dotted lines'ii'rlfig. 37. A

half revolution is then imparted to fork 44 causing the article and wrapper t'o assume the position shown in Fig. 6, During areturn longitudinal movement. of said rockshaft, the arm 23 travels above the station- I ary part 104. Rocking movement of shaft 12 causes u ward swmging movement-of said series o plunger arms, causmg'them to occupy the position shown in Fig. 2. It will be seen that in this position, plunger arm 20 stands to the rear of the article'and wrapper in fork v44, so that as forward Ion.-

gitudinal movement of the rock-shaft causes Iplunger arm 19 to repeat the operations previously described, the plunger arm 20 :WIll move the article and Wrapper out of the fork 44, and through the channel sectlon formed by canvas covered. plates 35 and 40,

whereby the lower plate 40 causes the down:

wardl extending portion d'of the wrapper to be olded upon the portion of the wrapper previously folded upon the article, as shown in Fig. 7. Said forward movement of plan'- ger arm 20 causes the article and-wrapper folding mechanism shown in Figs. 11, 15, 20,

22, 25, 27, 28, 30, 31, and 32, become operative. The article with the wrapper folded plate 41.

i a vertical rod 109 fitting in a guide 110. The.

t'ionary .threade to. receive nuts 118 whlch are adlower end of rod 109 is provided With a roller 111 which engages a cam 112 secured to the driving shaft, whereby said rod and frame 108 are caused to reciprocate vertically. J ournaled at each end of frame 108 is a shaft 113 to which is secured adownward extending swinging arm 114. Forming part of each shaft 113 is a crank 115 to which is pivoted a rod 116 which extends upwardly through holes formed in a stalate 117. The rods 116 are screw justed to a certain distance above the plate 117. Upon the upper ends of rods 116 are fitted weights 119 which aresupported by said nuts. Secured to each swinging arm 114 is a plate 120 having a downward extension 121 at each end thereof; The lower ends of said extensions have edges which are inclined at 122 in an upward direction to-' ward each other, and extending about half the lengthof the extensions, the upper ends of said extensions have edges which are in- I. clined at 123 in anupward'direction away fromeach other, whereby p rojections. 124 vare formed on. said extensions as'is shown in Figs. 11 and 15. The swinging arms 114 are connected by an elastic canvas band 125.

' Secured to each end of frame 108 is a down-.

ward-extending plate 126,"the lower end of which is provided with anarrow portion 127, which extends inward above one of said overhanging ends of thewrapper. The

weights 119 cause/the. arms 114 to swing away from each other until checked by the elastic band- 125 or-by engagement of the plates 120' with the downward extendingplate 126, as shown in Fig. 20. Downward movement of frame 108 causes the inward extension 127 of plates 126 to I fold sai.d" parts;-e and fold the upper portions 6 of the overhanging ends of'the wrapper to the position shown in Fig; 23. Further downward movement of frame 108 causes the inclinededges 1,22 ofplates 120 on swinging arms 114'to fold side portions f of said overhanging por- "tions ofthe Wrapper to the position shown infFig. 24.- Further downward movement 1 of "frame108 causes said elastic band 125 to f of the wrapper against th'eybeve'led ends 9 of the article.

causesfthe ar-ms114 and elastic canvas 125' to foldsaid overhanging ends of the wrap per againsta presser plate 128, as shown in Fig. 25, thereby causing said portions of the wrapper'tobe fol; the vposition shown in Fig. .26. I Presser plate 128 is'secured to a rod 129 having vertical movement in a I,

guide 130 and forc ed upward by means of a spring 131 which presses against a collar 132 secured to the rod.- As shown in Fig. 25,

the nuts 118 on rods 116 are resting on the stationary plate 117, so that as the frame 108 the position shown in Fig. 27. During said swinging movement of arms 114 the attached plates 120 take against the yielding presser plate 128, causing. downward movement thereof, thereby permitting .said arms to force the elastic canvas band 125 and said foldedportions of the wrapper toward the under sides of the ends of the article. During upward movement of frame 108 the weights 119 on rods 116 will-cause the arms 114 and attached plates 120 to swing back to of collar 132 against a stationary part of the machine. As shown in Fig. 28, said presser plate at the end of. its upward, movement serves to hold said foldedportions of the wrapper toward the under side of the ends of the article the bevel ends g, the elastic band-125 could In case the article to be wrapped hassquare ends, as shownin Fig. 30,, instead of be omitted, the swinging arms 114. then causingsaid portions of the Wrapper to be folded toward .the under side of the ends of the article. i

In case the article to be-wrapped has-little height,- the plates126 will be removed and folding of the overhanging. ends of the wrapper will be accomplished in the mannershown by Figs. 15., 31 and '32. Downward.

movement of frame 108 then causes the pro jections 124 on extensions 121' of plates'1-2O to fold side portlons .h 'of'said overhanging portions of i the wrapper to the position 1 shown in Figs. 32 and 33. Further down-. ward"m'ovement of frame 108 causes said.

elastic canvas band 125 to fold the parts a and 72, against the beveledends'g ofthe artifcle and also causes said parts. of thewrapper. to be folded against the presser plate' 128. The remaining operation being the same as that shown in Figs. 27 and 28, furfther description is not considered necessary.

When another forward longitudinal-movementv ofthe rock-shaft occurs, a third articleand wrapper will be' moved bylunger' ar'm19- into. fork 44, simultaneous y with Further, downward movement 'of' frame 108 movement of thesecondfart-icle and wrap.-

per into range with said. wrapper folding mechanism-by means i -plunger arm 20, and

simultaneouslvf wi-th movement by plunger arm 21 of the first article and wrapper against-the outer wrapperb which wrapper;

folded upon the wrapped article and A forced therewith into the fork 45, as shown By reference to Figs. 35 and 36 it will be in Fig. 11.

seen that during movement of the first article and wrapper afrom said folding mechanism to the wrapper b the foldglgp'or portions of the wra per to seat'themselves wrapped article and outer wrapper b to be against the fold o the .wrappei' on the underside of the article.

A half revolution of fork 45'causes the moved from the position shown in Fig. 8 to the position shown in Fig. 9, causing an upward extension of the outer Wrapper to rest against a roller 136. Roller 136 is journaled in the free ends of arms 137 which are pivoted at 138. J ournaled in the outer ends of arms 137 is a roller 139 which is located near the forward end of the vertically yielding upper plate 37. Journaled in lower,

plate 42 is a roller 140 which is located below roller 139. Journaled in a standard' ,141 is a shaft 142 to which is secured an arm 143 extending horizontally, and carrying a paste receptacle 144 at its outer end. Also secured to shaft 142.is adownwardly extending'arm 145-having a roller 146 at its lower end, which roller bears against a cam 147 secured to the driving shaft. J ournaled in the bottom-of paste receptacle 144 is a roller 148 having part of its surface in conratchet-wheel 150 which is engaged by a retact with paste 149 within the receptacle, and part ofthe surface of said roller being. outside of the receptacle.

Secured to one end ofyrollen 148 is a taining pawl 151 pivoted to the receptacle and also engaged by a pawl 152 which ispivoted to a stationary part of the machine.

A spring 153 causes the pawl 152 to be-held against the'lratchet wheel 150.- The cam 147 acting on arm 145 causes upward movement of the paste receptacle 144; roller 148, and

ratchet wheel 150, thereby causing'rotation of roller 148 by engagement of pawl 152 with the ratchet wheel. Said rotation of roller 148 carries paste out from the receptacle. Action ofcam 147 on arm 145 permits the receptacle to move downward,

thereby causing paste on the surface of roller 148 to be deposited upon said upturned portion 7' of the outer wrapper rests ing against the roller 136. 7

Forward longitudinal movement. of the rock-shaft will cause movement of articles and wrappers by the plunger armsin the manner previously described, and. will also cause the plunger arm .22 to move the wrapped article and partially folded and paste coated outer wrapper into the channel section formed by yielding upper plate37 and the lower plate'42. When this occurs the roller 139 will, cause the paste coated extension 9' of the outer wra per to be folded upon a previous foldo said outer wrapper as shown in Fig. 10, said paste serv- -ing"to hold said folds-of the wrapper tois secured, is a gear wheel 154 which is in mesh with a gear wheel 155. Gear wheel 155 is in mesh with a gear wheel 156 which is in mesh with a gear wheel 157 secured to a shaft 158. It will be readily seen that each intermitter it half revolution" of fork 45 will bydneans of said gearing cause intermittent half rovolutions of shaft 158' in a reverse direction.

Secured to shaft 158 are two chain wheels 159. Riding over each chain wheel 159 is anendless chain 160 which rides over a chain wheel 161 secured to a tube 162. Tube 162 is journaled upon a fixed shaft 163. Forming part of each chain 160 is a series of arms 164 so arranged that while the chain is at rest, said wrapped article is moved by plunger arm 22 to rest between two of said arms, as shown in Fig. 11. Then after the rock-shaft has caused downward and rearward movement of plunger arm 22, a half revolution'of 'fork 45 will cause a movement of chain 160,'by means of said in termediate connections, thereby causing an arm 164 on the portion of chain then passing over chain wheel 159 to engage and move said wrapped article from the. position shown in.Fig. 11 to the position shown in Fi 2. brush 165 pivotedat one end, is adwrapper, during successive-{movements of,

the wrapped article on the supporting plate 42. It will be evident that adjustment of plate 37 to any height will cause a like adjustment of the swinging end of brush 165.
